Answer

Explanation:

Step1: Analyze the procedure

The NumOccurrences procedure has a logical error. The inner count variable is re - initialized to 0 in each iteration of the loop instead of maintaining the cumulative count.

Step2: Check each option

  • For the list ["birch", "maple", "birch"] and target "birch", due to the error, it won't count correctly as the inner count is reset each time.
  • For the list ["birch", "maple", "oak"] and target "maple", it will have the same incorrect counting behavior.
  • For the list ["birch", "maple", "oak"] and target "oak", same issue.
  • For the list ["birch", "maple", "oak"] and target "spruce", since "spruce" is not in the list, the incorrect counting behavior still applies in the sense that the procedure won't work as intended.

Answer:

All four options will not return the intended value.
